Correct Answer: C

Rationale: The correct answer is C, 'pugnacious.' 'Belligerent' means aggressive or combative, which aligns with the definition of 'pugnacious.' Choice A, 'retired,' is incorrect as it does not relate to the aggressive or combative nature of 'belligerent.' Choice B, 'sardonic,' means grimly mocking or cynical, which is not synonymous with 'belligerent.' Choice D, 'acclimated,' means to become accustomed to a new climate or environment, which is unrelated to the meaning of 'belligerent.'

Correct Answer: B

Rationale: Choice B is incorrect due to the use of 'than' instead of 'then.' The correct word in this context is 'then' to indicate the order of actions. Choices A, C, and D are all grammatically correct. In choice A, the sentence structure is correct with a clear cause-effect relationship. Choice C is grammatically sound, describing the dietician's mistake. Choice D is also grammatically correct, showing a cause (the child feeling ill) leading to an effect (the nurse sending him home).

Correct Answer: C

Rationale: The correct answer is 'C: Laid.' 'Laid' is the correct past tense form of 'lay,' which means to put something down. 'Layed' in choice A is incorrect as the past tense of 'lay' is 'laid,' not 'layed.' Choice B, 'Drop,' is incorrect as it does not fit the context of placing something on the table. Choice D, 'Lay,' is the base form of the verb and does not fit the sentence in the past tense.

Correct Answer: C

Rationale: The correct answer is C: 'cause it to happen.' 'Implement' means to put something into action or cause it to happen. Choices A, B, and D are incorrect because they do not reflect the meaning of 'implement.' Preventing something from occurring (Choice A), emphasizing the importance of something (Choice B), and following something from beginning to end (Choice D) are all different actions or concepts that do not align with the definition of 'implement.'

Correct Answer: B

Rationale: In the context provided, 'dilation' refers to the widening or opening of the cervix during labor as the woman progresses towards childbirth. Choice A, 'Blood pressure,' is incorrect as dilation does not relate to blood pressure. Choice C, 'Birth process,' is too broad and does not specifically define the term 'dilation.' Choice D, 'Exhumation,' is unrelated and does not fit the context of the sentence.
